Must read: How to Convert String to JSON Object in Java
- easy to use;
- has familiar syntax;
- can be used in a wide variety of programming environments.
Outside of primitives, we have the usual control structures such as “if-else” statements which are used for branching logic for and “while loops” which are used to examine multiple objects in a list one at a time and “try-catch” statements which are used to handle unexpected errors during your program’s execution.
We use the terms “var”, “let”, and “const” to declare references to instances of primitives or objects. “Var” is outdated and rarely used. “Let” allows you to temporarily assign something that could be changed later. And “const” allows you to permanently assign something that will never change like the constant time.
Ability to work on different platforms and browsers. A skilled developer knows the intricacies of working on many platforms. Know where you need to fix something to make the product look complete on all browsers. So when a new platform for product promotion appears, the developer must study the features of working on it.
Communication skills. Yes, who would have thought, but no developer sits in silence for days on end. The ability to communicate with both the customer and the team is an extremely important trait of a professional.
There are other programs that would be good to know, now they are only gaining popularity (but we have already talked about trends). We are talking about Bootstrap or other frameworks, LESS, SASS.
JQuery. JQuery is an extremely productive library, I have absorbed plugins, extensions, and shortcuts that speed up some features.
What questions the developer must prepare to listen to during the interview?
Answer: Two, prototype inheritance (also: prototypes, OLOO) and functional programming (also: closing, functions of the first class, lambda).
- What can you say about functional programming?
- What is the difference between classical inheritance and prototype inheritance?
Answer: In the first type of inheritance, instances pass from classes and create relationships of subclasses. And in the prototype inherited, instances pass from other objects.
- What are the benefits of functional programming do you know?
Attention! What I wanted to draw attention to is that in most cases, the interview questions will be about functional programming. So if you want to impress your employer, then study this question a little more.
Answer: functional programming greatly simplifies the development process, the quick finding of the problem and options for its solution, etc.
- When should you choose a prototype inheritance?
Answer: When functional programming does not find a solution to the query; when the object consists of more than one source; when inheritance is needed.
- The difference between two and one-way data binding?
Answer: Two-way data binding is special in that when any changes are made to the code, they are automatically displayed on the product interface.
With one-way data binding, only the model can make changes (it manages everything).
